Question #2: (20 points) Three single phase two-winding transformers each rated 400 MVA 13.8/199.2 kV with leakage reactance Xeq=0.1 pu are connected to form a Y-Y three phase bank. Winding resistances and exciting current are neglected, three phase load operating under balances positive sequence conditions absorbing 1000 MVA at 0.9 power factor lagging at high voltage side with VAN= 199.2 (angle zero), find the low voltage bus line to neutral Van=? (Do all calculations in per unit)
